' ROLL-OVER MECHANISM FOR MOLDING-MACHINES.

Specification of Letters Patent.

Patented Oct. 29, 1918.

Application filed December 10, 1913. Serial No. 805,687.

To all whom, it may concern:

Be it known that I, JOHN T. STONEY, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a certain new and useful Improvement in Roll-Over Mechanism forMolding-Machines, of which the following is a full, clear, and exactdescription. I i

This invention relates to molding machines and has for itsobject theequipping of a molding machine having a table which I ring table, .orplatform 1, which is mounted upon a cylinder 2, and if desirable may beformed integral with the jarring table. At

its lower portion, the cylinder 2 is provided .with a flanged portion 3,which 18 adapted to contact with a base or anvil 4. Through the flangethere are openings 5, through movement of the table.

Extending upwardly from the base 4, within the cylinder 2 is a piston 8,the p1s- .ton forming a guiding means upon which the cylinder 2 mayreciprocate. In the cylinder 2, at that portion which lies above thepiston 8 is an opening 9 .which may be connected with a supply ofcompressed air, which will be regulated by a suitable valve mechanism,(not shown) so that the cylinider 2 and table 1 may be jarred or air maybe continuously forced between the cylinder and piston so as to raisethe table 1, as far fats-permitted by the guide rods 6.

Mountedupon the table 1 are spaced uprights 10, which at their upperends are provided with journals in which are seated short shafts 11.These shafts at their inner ends are secured to the side arms 12, of amolding table, or flask support 13. It will thus be seen that the shafts11 in effect form trunnions for the swinging molding table 13.

In the particular instance shown, there is upon the bottom of themolding'ta'ble, or support 18, a foot 14, which is adapted to engagewith a stop or rest 15 carried by the jarring table 1.

Upon the outer end of each shaft 11, there is secured a wheel 12, andsecured to the wheel is a sprocket chain 13?. This chain extends alongthe periphery of the wheel for a certain distance, and preferably the:wheel 12 is grooved to receive the chain 13".

The end of the chain is fastened to a rod 14 which may convenientlyextend down into the pit in which the molding machine is usuallymounted, and is adapted to extend through an opening in the bracket 16.Upon the lower end of the rod 14 is an adjustable nut 17 to limit theamount of play which the rod 14 may have with respect to the bracket 16.i

The operation of the device is as follows:

hen the table 1 is raised by the admis sion of air between the piston 8and the cylinder 2, the rod 14 is lifted in the first instance, untilthe nut at the bottom thereof engages with the bracket 16. At this time,the rod 14 and chain 13 are held against further movement, and soproduce a rotation of the wheel 12, thus causing the shafts 11 to turn,and thereby the molding table 13.

There is provided a stop 18, which limits the movement of the arms 12,so that the same will be held in upright position.

There is also a spring pressed plunger 19 which is adapted to cooperatewith suitable openings 20 formed in the one arm 12 so that the table 13'may be locked either in its inverted position or in its normal positionwhen the foot 14 and the rest 15 are in engage'mentr The reason forallowing some play between the end of the rod 14 and the bracket 16 isthat the table 1 may be jarred without putting any strain upon the rod14.

' Having thus described my invention, what Iclaim is:

1. In a machine of the character described, the combination of aflask-support; means for raising said support; and means for turningsaid support relatively to said raising means, said last-named meansineluding a member made up of a plurality of linked parts anchored-atone end and connected with said support eccentrically of its .means forraising said support; and means for turning said support relatively tosaid raising means, said last-named means including a rotatable memberconnected with said support and a flexible member anchored at one endand connected with said rotatable member at the other.

3. In a molding machine, the combination of a roll-over molding table;means for raising and lowering said table; and a flexible member securedat one end with respect to said table, the opposite end of said flexiblemember being securedto said table to cause the same to'roll over as itis elevated.

4. In a molding machine, the combination of a roll-over table; means forraising and lowering said table; an annular member connected with saidroll-over table; and a flexible member cooperatin with-said annularmember, one end of saic flexible member being held against anysubstantial movement, whereby the table is rolled over,-as it is raised.v

5. In a molding machine, the combination of a molding table; uprights inwhich the said table is trunnioned; supporting means for the uprights;means for raising and lowering said supporting means; anda flexiblemember adapted to extend arounda trunnion of said molding table, one endof said flexible member being secured against substantial movement,whereby said table is rolled over, as the support is raised.

,6. In a molding machine, the combination of a molding table;supports-inwhich sald table is'trunmoned; means for raising and loweringthe said supports; an annular member mounted on each of the trunnionsfor the table;- and a flexible memberconneeted to each of said annularmembers and extending around the same, the opposite ends of saidflexible members beingsecured so as to be relatively immovable withrespect to said molding'table. 1 or 7. In a-molding machine, thecombination of a roll-over table; means for raising and lowering saidtable; an annular member connected with the roll-over table; and aflexible member, one end of which .is secured to and cooperates with thesaidannular -member, the other end of said flexible memher having aslight amountof movement as the table is raised, but eventually becomingfixed, whereby the table is rolled, over as it is raised. 1

8. In a molding machine, the combination with a jarring table; of aroll-over. table; means for raising and lowering said rollover table; anannular member connected with the roll-over table; and a flexiblemember, one endof which 1s secured to and cooperates with said annularmember, the

other end of said flexible member having a slight amount of movement topermit the jarring action, but becoming fixed as the roll-over table israised, thereby to cause the said table to roll over as it is raised.

9. In a molding machine, the combination with a jarring table; of aroll-over molding table; means for raising and lowering said roll-overmolding table; an annular member connected with the molding table; aflexible member, one end of which is secured to and cooperates with theannular member, the other end of said flexible member being providedwith a head; and a stop member with which the said head cooperates whenthe said roll-over molding. table is raised, whereby the roll-overmoldingtable is rolled over as it is raised, said stop and head having alimited amount of play whereby the roll-over molding table may jar withthe jarring table without affecting the said flexible member.
